Sirio Gain-Master – Fiberglass CB Base Station Antenna 7.36 m

The Sirio Gain-Master is a high-tech fiberglass base antenna for 27 MHz (CB radio) and the 10 meter amateur band — a 0.625 center-fed vertical dipole designed to get the maximum gain obtainable for a base antenna. The patented center-fed dipole puts all RF parts of the antenna in phase, so no side radials are needed.
